Low Power Design of 40 Gigabit Ethernet Media Access Controller Using Hyper Transport ProtocolIO Standard

Nowadays, the low power design requirement for
the communication equipment is becoming essential for green
communication systems. The Ethernet Media Access Controller
(EMAC) is an important source interfacing the physical devices.
However, the high-speed data operation consumes an enormous
power. This limits the performance of existing Ethernet Media
Access Controllers in real-time. In this work, a novel low power
design of 40G EMAC is developed using Hyper Transport
Protocol (HTP) IO standard technique. The designed 40G EMAC
is developed using Xilinx and tested for high frequencies of 5
THz, 10 THz, and 15 THz. The developed 40G EMAC using HTP
IO standard is consuming less power for THz frequencies. It is
also demonstrated that 70% power reduction is archived for
5THz, and for 10 THz and 15 THz, 69% and 68/% power
reduction is attained respectively for 40G HTP based EMAC.
The developed EMAC can be used in existing communication
system in order to make the green networking.
